Hemodynamic and Stress Response After Sound Intervention with Different Headphone Systems: A Double-Blind Randomized Study in Healthy Volunteers Working in the Health Care Sector.

Two headphone systems using different sound systems were compared to investigate the effects of a sound intervention on cardiovascular parameters, indicators of stress, and subjective feelings. One hundred volunteers who work in the health care sector reporting elevated workplace-related stress were enrolled and randomized to a 12-min sound intervention (classical music) with either conventional headphones ("MEZE 99 Classic") or with the same-but internally modified-headphone (called "Lautsaenger"). Cardiovascular parameters were measured with the VascAssist2.

Effects of a Sound Intervention on Physical and Emotional Well-Being in Patients with Cancer: A Prospective Randomized Trial.

Aim: Cancer remains a disease with a significant impact on morbidity and mortality but also on quality of life. This prospective randomized pilot study investigated the effects of a sound intervention on physical and emotional well-being in outpatients with cancer.

Methods: Two self-applied sound interventions were used for this purpose, either active "music playing" with a body monochord or passive sound intervention with headphones to listen to a given music compilation.

Differential Effects of Sound Intervention and Rest on Cardiovascular Parameters in Cancer Patients: A Randomized Cross-over Trial.

Background: Music therapy or sound interventions were shown to confer beneficial effects in patients with cancer for instance in terms of pain or fear relief and improvement of other patient reported outcomes. Cardiovascular parameters, especially heart rate variability (HRV) were found to have prognostic implications in cancer patients. In this trial we aimed to investigate the effects of a sound intervention on cardiovascular parameters compared to rest in patients with cancer.
